Last year, 37signals introduced two HTTP proxies: Thruster and Kamal-proxy, which have overlapping features. Thruster is designed specifically for serving Rails applications and is lightweight, effectively "wrapping" around a single application process. It’s ideal for quickly deploying proof-of-concept apps without the need for load balancing or zero-downtime updates. Users can easily set it up with minimal configuration by defining a TLS_DOMAIN for automatic SSL/TLS and using a simple command to launch their app

In an April Fools' joke post, Justin Le humorously addresses the challenges faced by Haskell enthusiasts when forced to write in other programming languages. He suggests that the concepts of Algebraic Data Types (ADTs) and Generalized Algebraic Data Types (GADTs) are so foundational that they can be adapted to various languages, despite potential quirks or unconventional methods. Le explains that ADTs consist of products (immutable structs) and sums, and emphasizes the importance of using appropriate patterns,

The article by Andrew Walsh, creator of openapi-devtools and Demystify, discusses the challenges developers face regarding API documentation. Poor or nonexistent documentation can severely hinder productivity, increasing frustration and errors. While documenting APIs is important, it can be complex and time-consuming, especially under tight deadlines. To address these issues, various solutions have emerged that automate API documentation. Some libraries, like drf-spectacular, infer API contracts from code structures, while frameworks like FastAPI and Huma generate Open

The content introduces Eventually Green Tests (EGT), an innovative software testing approach inspired by the concept of eventual consistency in distributed systems. EGT posits that failing tests will resolve themselves over time through various scenarios: either the code will align with the tests, the tested features may become obsolete, existing tests will become irrelevant due to major code base changes, or an entire application may be deprecated. A study from FAANG companies supports the approach, noting that 97% of failing tests either eventually pass or

The abstract reveals that the author discovered that the commonly accepted exponential dependence of resistivity on temperature in germanium is misleading. The author criticizes both their equipment and existing literature, deeming the effort a waste of time. In the introduction, the author discusses the concept of electron confinement in energy bands in germanium and explains that heating the material allows electrons to transition to conductive bands, which supposedly affects resistivity in an exponential manner, though the author dismisses the complexity of the theoretical background. The experimental

The author reflects on their experience with AI tools, particularly in coding and development. They first used AI in late 2022 and were initially impressed with its capabilities, especially for debugging. Over time, however, they noticed a decline in their own coding skills as they increasingly relied on AI integrations like GitHub Copilot in their workflow. By late 2024, the author decided to remove these AI tools, even though they still occasionally use AI and see its potential benefits for programmers. The author compares

The content discusses several important laws and principles that are relevant and useful for engineers and engineering managers. The laws highlighted include: 1. **Parkinson’s Law**: Work expands to fill the available time, which can lead to unrealistic deadlines. 2. **Hofstadter’s Law**: Projects take longer than expected, even with buffer time, highlighting the challenges of accurate estimation. 3. **Brooke’s Law**: Adding manpower to a late project makes it later, illustrating that simply increasing

The author has developed a CLI tool called Advent of Ruby for participating in Advent of Code using Ruby. Initially hesitant to join the event due to self-doubt and stress, they found enjoyment in solving past puzzles at their own pace. To streamline the process, which involved juggling multiple files and tabs for input, solutions, and submissions, the author created the tool to automate these tasks. Building on an existing utility gem (AoC-rb), they added two new commands for committing solutions and tracking progress.

The content discusses the recurring hype surrounding conversational interfaces in technology, which emerge periodically with claims that they will revolutionize computing by enabling natural language interaction. Despite these predictions—marked by the introduction of virtual assistants, smart speakers, chatbots, and large language models—there has been little substantial change in how we interact with computers. The author speculates that this fascination may stem from a longing for a future envisioned in science fiction or an assumption that "natural language" is the ultimate goal of technology. However

The Netflix Technology Blog discusses the challenges of transitioning from script to screen in the film and television industry, particularly with the shift to cloud-based workflows. While this transition promises benefits like improved media management and a focus on creative storytelling, obstacles remain, such as managing vast amounts of data generated during production and the inefficiencies of traditional media storage methods like physical tape. To address these issues, Netflix has created the Media Production Suite (MPS), a set of tools designed to streamline media logistics and enhance collaboration within

The author expresses skepticism about the current hype surrounding AI in software development, describing it as driven by Fear, Uncertainty, and Doubt (FUD). They criticize the rush among companies to adopt AI features without careful consideration, driven by a fear of missing out. Reflecting on their own early programming experiences, the author contrasts these with modern developments, recalling the challenges of learning to code without today's conveniences such as syntax highlighting and online resources. They highlight the significant improvements in development tools over the years,

The content discusses the behavior of the Intel 8086 processor when it receives an instruction that doesn't exist. Unlike modern processors (such as the 80186 and later), which generate an exception for illegal instructions, early processors like the 8086 lacked the capability to detect such errors due to design limitations. As a result, the 8086 may perform unspecified actions in response to illegal instructions, including executing some undocumented commands that can reveal hidden internal register values. The 8086 uses microcode,
